can COUPLING.

Application filed March "7, 1923. Serial No. 623,325.

T all whom it may concern:

Be it known that l, HARRY M. Bnowiv, residing at New liens ngton, in the county of 'll estmoreland and State voi" Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in (arCouplings of which i1nprovcments the following is a specification.

My invention relates to the construction of a coupler head for cars adapted to be drawn in trains, and, while not so limited, 1 have developed it in application to cars used for carrying hot metal, slag, etc., in steel-manufacturing plants. i

In the accompanying drawings Fig. I is a view in elevation, showing tragnientarily the bodies of two adjacent cars coupled together, equipped at their meeting ends and coupled by means 0:"- identical' coupler heads in which coupler heads my present invention is embodied. In this figure one of the two identical coupler'heads'is shown in section, on vertical and medial plane. Fig. II is a view of the same assembly, seen in plan tirom'abov'e, and here one coupler head is shown in horizontal and medial plane. Fig. 111 is a View in vertical section, on the transverse plane indicated by the line ILL-III, Fig. l. y r

In Letters Patent of the United States No. 1,429,186, granted me September 12, 1922, I have described and claimed certain features of coupler construction, and the coupler head in which my present invention is found is of the general type shown in those Letters Patent.

In the drawings which accompany and form part of this specification the bodies of the two cars coupled together are indicated at 1 and 2. To the sill plates or end timbers of these car bodies the coupler heads are directly bolted. The coupler heads are of bull-nose type, with outwardly flaring open noses, adapted to receive and guide an entering coupling link, and after coupling to allow lateral pivoting of the linkwithin the head. These heads are indicated by the numeral 3. They are provided with laterally extending basal flanges 4, by means of which they may be bolted, as 'has been said,

to the framing of the cars.

A coupling link 5 is Shown, uniting the two cars, and it is engaged at either end by a hook of one ol the two coupling heads. The hook 10 is pivoted for vertical swing within the head 3 ona pivot admitting of longitudinal play of hook relativeto head,

and the hook at its forward end is notched,

as at 15, to admit of swing during coupling" This iriatteraiicl the shaping of the anterior and 1 posterior link-engaging I faces of hook 10, all of them explained in the specification of my earlier patent, are -maniiest, and need only be noted here. Y

I As in the coupler head ent the space within which :the pivoted hook swings is hooded over, indeed it is wholly encased in the boss, or upward extending bay 6, with walls continuous with of my-earlier patthe walls of the. head. This boss all'ords i complete protection to the working parts of the coupler head; spilled or spashed molten metal, falling upon the coupler head, may not gain access, nor'inay such metal on cooling parts. H a

The book 10 is engaged from beneath, and preferably at a relatively short interval from its pivot point (which, as has been extreeze together relatively movable plained, is,'within. a narrow range, movable tended, as in traction,to cause it to recedej again within its range of play, and so, even though otherwise in locked position, to be ready to be swung-t0 unlocked positionwithout hindrance.

The construction which I now" have described admits of being built of minimum depth, in direction of the length of the car, that is to say,iol:' minimum over-allprojection from the car frame. The'structure may be built, as shown in the drawings, with no extension rearward beyondthe pivot po nt of the coupling link. At that point the structure is, so to say, out square off, and

the lateral flanges 4 are built out, through which thestructure may be bolted to, the car frame. The tongue 7 of spring steel, se-

cured at its anchored end by a screw 21, ex-

tends downward between the rear face of the structure and the face of the car frame against which it is bolted, and then turning upward extends to engagement from beneath with hook 10, as already explained. The uncoupling rod 8 is suitably journalled in the car frame.

The head being so truncated may be made of a minimum number of parts, easily assembled. The head is open to rearward, as indicated at 22, and through this opening the hook may be introduced and when seated may be secured by application of strap spring 7. Furthermore, the pivot pin 23 on which hook 10 swings may be cast or forged, integral with the hook itself, and make pivotal bearing forwardly upon properly disposed surfaces within recess 22.

I have, in order to afford fullest showing of the coupler head in which my invention is found, shown the meeting ends of two cars to be equipped, both with these heads. This is preferable in the steel-plant use which I primarily contemplate. Manifestly, however, the head in which my invention resides may cooperate with a head of any other type capable of engagement with an ordinary coupling link, such as that indicated at 5.

' The coupler head of my present invention is applicable for service in various places and is'not limited to steel-plant service, although I primarily contemplate service there. 7

I claim as my invention:

1. A coupler-head of bull-nose type whose upper wall is imperforate and closed against the ingress of any foreign substance, open rearwardly, and provided within and towards its anterior end with a vertically disposed bearing surface, combined with a hook adapted to be introduced from the rear intO the coupler-head and when so introduced un-' der traction adapted to bear upon said strain-sustaining surface.

2. A *coupler head of bull-nose type open rearwardly and provided internally with a pivot seat, combined with a hook capable of introduction from the rear to its pivot seat within the head, and a strap spring closing the rear opening and engaging the seated hook and tending to hold it rearward upon to hold it rearward within the coupler head and means. for pressing the spring and swinging the hook'upwardly from closed to .7

open position. a

In testimony whereof I have hereunto set my hand. a HARRY M. BROWN,
